Application filed October 11, 1913. Serial No. 794,748.

To all whom it may concern:

Be it known thatl, WILLIsH. CARRIER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in N ozzle-Flushing Mechanisms for Air and Gas Washers and the like, of which the following is a specification.

This invention relates to improvements in air and gas washers and analogous apparatus in which air or as is washed or conditioned by being broug t into contact with water discharged from spray or distributing nozzles.

The objects of the invention are to provide efficient means for flushing the Water discharge nozzles to prevent the same from becoming clogged by impurities in the water; also to provide efficient and practical means whereby the nozzles are flushed automatically at predetermined intervals of time, which can be readily controlled as may be desired or necessary; also to produce a flushing nozzle of simple and practical and desirable construction.

In the acqompanying drawings, consisting of three sheets:

Figure 1 is a fragmentary sectional plan view of an air or gas washing apparatus embodying the invention.

Fig. 2 is a longitudinal sectional elevation thereof.

Fig. 3 is a transverse sectional elevation thereof.

Fig. 4 is a fragmentary transverse sectional elevation thereof in line 44, Fig. 2.

Fig. 5 is an enlarged sectional elevation of one of the water discharge nozzles.

Fig. 6 is an enlarged section of the valve which controls the flushing of the nozzles.

Like reference characters 'refer to like parts in the several figures.

A represents the washing chamber of an air or gas washing or conditioning apparatus through which the air or gas may be caused to flow by any suitable means not shown, and B represents nozzles for discharging water into the chamber A for washing or otherwise conditioning the air or gas. C represents spaced'zig-zag eliminator plates of ordinary construction for removing the free water from the air or gas betwo chambers ratus and the use for which it is intended. As shown, the nozzles are connected by lateral branches 0? and upright pipes d to a main supply pipe d Each of the discharge nozzles is preferably constructed as shown in Fig. 5. As there shown the body of the nozzle is divided into 6 and b by a transverse diaphragm b of rubber or other suitable material, the body being preferably formed of two hollow shells or parts 6 6 provided with flanges b which are connected by bolts 6 and between which the diaphragm is clamped and secured. The shell 6 is connected, preferably at one side, with the water supply pipe 03 and is provided with a tapered or contracted open end through which the water discharges. E represents a distributing disk which is located just in front of the discharge end of the nozzle so as to cause the waterto spread and discharge in the form of a, thin sheet through the narrow annular space'between the disk and the end of the nozzle. The distributing disk is secured to the outer end of a rod or stem 6 which extends into the nozzle and is secured at its inner end to the diaphragm b which is adapted to be actuated to move the disk toward and'from the end of the nozzle. The area of the diaphragm b? exposed to the pressure of the water in the larger than the area of the distributing disk exposed to the water pressure and the pressure of the water in the chamber 6, therefore, tends to move the disk inwardly and hold it normally close to the end of the nozzle, as shown in Fig. 5. The distance of the disk E from the end of the nozzle is regulated to control the discharge of water from the nozzle by a suitable adjustable device, such, for instance, as a set screw G which limits the inward movement of the diaphragm .and the disk E by engaging the inner end of the stem 6. By adjusting the set screw inwardly or outwardly the distance of the disk E from the end of the nozzle can be increased or'decreased as may be desired.

H represents a pipe for admitting pressure, either liquid or fluid, from any suit able source to the chamber 5 in rear of the diaphragm b for actuating the diaphra to move the disk E away from the end of the nozzle so as to permit a considerable volume of water to be discharged for flushing the nozzle or clearing out any matter which may have collected in and obstructed chamber 6 is,

the narrow passage between the end of the nozzle and the disk E. If the pressure on the rear side of the diaphragm 1) equals or exceeds the pressure of the water on the front side of the diaphragm, the pressure of the water on the disk E will move the same outwardly. Thus the diaphragm can be actuated to move the disk E outwardly for flushing the nozzle by admitting to the chamber 1) water under the same pressure and from the same source as the water which is discharged by the nozzle. The admission of the pressure fluid to the chamber 6 for flushing the nozzle can be controlled by any suitable valve or device operated either by hand .or automatically. Preferably, however, all of the nozzles B are flushed periodically by a common automatic controlling mechanism, the mechanism shown for this purpose being constructed as follows:

The pipes H for the several nozzles B are connected by flexible hose h, upright pipes h, and a pipe h to a main .pressure supply pipe it provided with a valve I for controlling the pressure to all of the nozzles. The valve I shown, see Fig. 6, slides in a casin i and is adapted when raised by a spring '21 to cut oil? the fluid from the supply pipe 72. and connect the pipe k to a discharge opening 2' to allow the water to drain from the chamber Z). By depressing the valve the discharge opening 1' is closed and the pressure fluid is admitted to the pipe h and nozzle chamber 1).

K represents a dumping pan or receptacle arranged in the washing chamber A in position to catch water discharged from one or more of the nozzles B. This pan is secured to a rock shaft is provided with a weighted arm k which is normally adapted to hold the pan K in position to receive and retain the water. the pan K to overcome the counterbalancing weight, the pan will tip and discharge the water and by this movement actuate the valve 1. YVhen the pan is emptied the weight will again turn the pan to its receiv 7 ing position, the welght being adapted to rest against a suitable stop or support 10 when the pan is in its normal recelvmg pOSltron. L represents an adjustable shield or deflector over the pan K. By adjusting this shield it is caused to cover the pan more or less, thereby determining the length of time required for enough water to collect in the pan to tilt it. The valve I can be actuated by the tilting of the pan K through any suitable connection. As shown the projecting end of the valve stem is engaged by a lover or arm M which is pivoted at m on a bracket extending from the valve casing and is connected by a link m to an arm on the rock shaft to which the pan K is connected.

\Vhen sufficient water collects in nozzle and to be moved by When the pan is tilted by the weight of the water therein it depresses the lever against the action of the valve returning spring and moves the valve to connect the pressure supply pipe h with the pipe k leading to the nozzles thereby admitting pressure to the chamber 12 of the nozzles. When the pan is returned to its normal receiving position by its counterba lancing weight the valve is returned by its spring to a position in which it cuts off the pressure supply pipe h and connects the pipe h with the discharge opening i thus ermitting the water to discharge throug 1 the pipe and valve from the chambers b of the nozzles and relieving the pressure on the rear side of the nozzle diaphragms b By the described mechanism the nozzles will be flushed periodically whenever sufficient water collects in the pan K to tilt it,

,. and the interval of time between the flushings can be governed the shield L.

- liquid discharged by said nozzle and tobe moved by the weight of the liquid collected therein, means actuated by said pan when moved for enlarging the discharge opening of said nozzle, and a shield for said pan which is mounted independently of the pan and is adjustable relatively to the pan to intercept more or less of the liquid going to said pan for varying the operating periods of said pan, substantially as set forth.

2. In an air washing apparatus, the combination of a discharge nozzle for the washing liquid having a normally restricted discharge opening, a pivotally mounted pan arranged to receive liquid discharged by said the weight of the liquid collected therein, means actuated by said pan when moved for enlarging the discharge opening of said nozzle, and a pivotally adjustable shield over said pan for regulating the delivery of liquid to said an for varying the operating periods of said pan, substantially as set forth.
